Which maintenance strategy uses real-time sensor data and condition indicators to determine when to service equipment rather than following a fixed schedule?
Answer: Predictive maintenance
Predictive maintenance uses condition-monitoring data (vibration, temperature, performance trends) to predict impending failure and schedule service at the optimal time.
A hospital steam sterilizer (autoclave) fails its Bowie-Dick test on Monday morning. What is the immediate correct response?
Answer: Take the sterilizer out of service and notify sterile processing management
A failed Bowie-Dick test indicates air removal or steam penetration failure; the sterilizer must be removed from service immediately until the cause is identified and corrected.
Under NFPA 99, which type of medical gas outlet requires a minimum of two turns to open and a specific tool or key to prevent accidental activation?
Answer: Quick-connect station outlets in patient care areas
Quick-connect outlets in patient care areas must be designed with safety features to prevent accidental gas release, but NFPA 99 requires that manual zone valves can be shut off without tools — the question highlights the design intent to prevent accidental actuation at the point of use.
A preventive maintenance program uses an Equipment Risk Score (ERS) to prioritize devices. Which factor is NOT typically included in calculating ERS?
Answer: Device acquisition cost
Standard ERS models (e.g., Fennigkoh-Smith) use function, physical risk, and maintenance requirements — acquisition cost is a financial metric unrelated to clinical risk scoring.
Which organization requires healthcare facilities to maintain a written Utility Systems Management Plan that includes medical equipment?
Answer: The Joint Commission (TJC)
The Joint Commission's Environment of Care (EC) standards require a comprehensive Utility Systems Management Plan covering critical utilities and medical equipment.
A 10-year-old patient ventilator has reached end of manufacturer support with no available spare parts. What is the best facilities engineering recommendation?
Answer: Initiate capital replacement planning and escalate to clinical leadership
Obsolete life-critical equipment without parts availability poses unacceptable patient risk; the correct action is formal replacement planning with clinical and administrative leadership involvement.
What is the primary purpose of a Ground Fault Circuit Interrupter (GFCI) in a patient care wet location?
Answer: To interrupt power within milliseconds when leakage current exceeds a safe threshold
GFCIs detect imbalances between hot and neutral conductors (indicating leakage to ground) and trip within ~25 milliseconds to protect personnel from electric shock.
